Device /dev/sdb1 not found (or ignored by filtering)

Solution 1:

The partition type in the MBR is set to "ee" meaning that there should be a GPT partition table on the disk, but as parted shows, there isn't a GPT table at all.

You need to either:
a) use parted to make a GPT partition, and use that partition as the PV
b) remove the partition table from the MBR altogether and just use block device /dev/sdb as the PV

Solution 2:

I found that I either needed to reboot the server or run 'partprobe /dev/sdaX' in order for pvcreate to be properly informed of the partition.

Also, fdisk is not lvm aware so it was handing out errors about partitions making me think there was a bigger problem when that was simply not the case.

Solution 3:

Please run the below command before pvcreate

partprobe /dev/sdb

Then run your command

pvcreate /dev/sdb1

Note : Sometimes you need to update your kernel manually. Thats why the above command required.

Solution 4:

The block device type could also be a problem. If you run pvcreate with -vvvv and you see an error like "Skipping: Unrecognised LVM device type 251", then you have to add the magic number to the allowed devices list.

Just look up the device type for the number in /proc/devices and add it to the devices section of the lvm config /etc/lvm/lvm.conf, for example:

types = [ "bcache", 251 ]

That's it, you can now use pvcreate as expected.

Solution 5:

Your parted output shows that you don't have any partitions, thus /dev/sdb1 doesn't exist. You need to create the partition first.
